Holley Pro Series carburettors deliver awesome performance on the drag strip. They’re factory calibrated for competition engines and best of all they are ready for the strip right out of the box. The new HP carbies provide excellent throttle response for super category racing. New metering blocks features improved main metering circuitry with additional air bleeds for more complete fuel atomisation. This double leanout system will promote and maintain a far more combustible air/fuel mixture at high RPMs for maximum top-end horsepower.
